LOADING APPARATUS.

Application filed November 17. 1913.

To alt whom it may concern Be it known that I, Fnnn E. Axnnnsoiv, a citizen of the United States, residing at Osage City, in the county of Osage and State of Kansas, have invented certain new and useful Improvements in l ioading Apparatus, of which the following is a specification.

My invention relates to apparatus for loading manure, dirt, etc., into vehicles.

It comprises a frame, alongside of wh ch the vehicle is placed, a carrier, a frame pivoted in the main frame for raising the carrier from the ground and to bring the carrier above the vehicle or wagon bed, and certain devices for dumping the load in the carrier into the wagon bed; it also has a door along one side of the carrier for pre uniting the load therein from spilling until the final dump into the wagon bed is to be accomplished, with means for automatically operating the door.

It also comprises the parts, improvements, and combinations hereinafter set forth and claimed.

The object of my invention is to construct a simple, economical, durable, and easily operated apparatus of this kind, using few and simple parts.

In the drawings accompanying and forming part of this specification and in the description of the drawings, I have shown my invention in its preferred form and what I deem to be the best mode of applying the principles thereof; but it is to be understood that, within the scope of the appended claims, I contemplate changes in form, proportions, and materials, the transposition of parts, and the substitution of equivalent members, without departing from the spirit of my invention.

Figure 1 is a side elevation of a loading apparatus made in accordance with the principles of my invention, with a dotted outline of the carrier in final dumping position. Fig. 2 is a rear end elevation. Fig. 3 is a plan view. Fig. 4 is an enlarged sectional view on a plane indicated by the line 4 in Fig. 3. Fig. 5 is a sectional plan on a plane indicated by the line 5' in Fig. 4. Fig. 6 is a section on the line 6 in Fig. 4.

Similar reference characters indicate like or corresponding parts throughout the several views.

In constructing the main supporting frame, I lay out two beams 1, 1, extending Specification of Letters Patent.

from front to rear. By front I mean the end of the apparatus at which the carrier is located when down; and by rear I mean the end alongside of which the wag'on is driven to receive the load. These terms as used in this specification are only relative. The two beams rest on cross beams 2, 2 at front and rear respectively. At the rear end are placed two vertical angle bars 4, 4, reinforced by means of diagonal braces 60. The two beams 5, 5 rest at their front ends on the front ends of the beams 1, 1, respectively, and thence extend upwardly and rearwardly, being supported at their rear ends by the uprights 4, 4, respectively, and supporting, in turn, the cross-piece 6. This crosspiece has two upwardly extending fingers 7, 7; and the two arms or fingers 8, 8 extend laterally from the outer sides of the diagonal beams 5, 5, respectively.

9 is the main pivot rod to which the carrier-raising frame is pivoted.

The carrier-raising frame is constructed as follows: The two bealns 10, 10, pivoted on said rod 9, fit just inside the beams 1, 1, re spectively, and are connected and the frame made rigid by means of the diagonal braces 11, the cross-piece 12 at their rear end and the cross-piece 13 on the under side of their front end.

The carrier has a flooring 14 supported on cross-pieces 15, 15, two of which are located just inside the beams 10, 10, respectively, and two of which are located outside those beams and spaced apart therefrom sufliciently so as to be entirely clear of the main supporting frame, they being indicated by the numerals 16, 16 and are of extra length as shown in the drawings. A short cross-piece is secured to the flooring just outside each beam 10, as shown at 19, 19; and the carrier is pivoted to the carrierraising frame by means of bolts 18 passing through the front ends of the two beams 10, 10, respectively, and the adjacent crosspieces. In Fig. 3 the flooring is partly broken away to show this arrangement.

The carrier platform is provided at each side with a run-way 20 to guide the load thereonto.

At the rear edge of the carrier platform is a door 21 hinged thereto by means of countersunk hinges 22, 22. On the rear or under side of the door are two angle bars 23, 23, one adjacent to each of the beams 16, 16 of extra length and projecting down the cross-beam 13 of the alongside the same. 25 is a splice secured to each of these cross-pieces 16 to reinforce it and to provide in connection with the adjacent cross-piece a broader support for the plates 26, 26, which are spaced apart by means of spacers 27, 27, and secured to the cross-pieces by means of bolts or lag-screws 28, 28. Pivoted at 30 between the two plates is a latch 29, substantially L-shaped, which is adapted to extend, when in normal position, in the path of the angle bar 23, to hold the door in upright position. A stop 31 limits the movement of the latch, which is moved to its locking position by the extension spring 32. lVhen the extended handle of the latch is moved against the tension of the spring (to the left as viewed in Fig. 5), the latch is thrown out of engagement with the angle bar 23 and permits the door to fall open and down until it rests upon the projecting ends of the extra-length cross-pieces 16, 16, in which position it is in a plane with the main platform of the carrier.

33, 33 are two guides secured to the diagonal beams 5, 5, respectively, for bringing the door to upright position when the carrier is lowered, in which case the spring automatically locks the latch and thus holds the door in upright position until the handles are again operated, as will be hereinafter described.

34, 34 are two short angle bars secured to the under side of the carrier platform at the rear edge thereof by any suitable means as by bolts 35, 35, and located outside the main supporting frame. Each of these angle bars has a hole 36 in its rear end, near the rear edge of the platform. To this hole is secured a chain 37, there being one such chain on each side of the main frame, the rear ends of the chains being secured to the main frame a little above and to the rear of the pivot bolt 9, the manner of securing being preferably by means of U-bolts secured to the respective uprights 4 as indicated at 38, 38.

Any suitable means may be used for elevating the carrier-raising frame and carrier. I have shown a simple form of compound pulleys. There are four pulleys 40 secured to the cross-beam 6 of the main supporting frame, and a similar number, 41, secured to carrier-raising frame. A cable, secured at one end by passing it through the cross-beam 6 and knotting it, as shown at 42, is thence passed over the several pulleys, and thence to the 'pulley 43 secured to the cross-beam 2 at the rear of the main supporting frame, and thence outwardly in any convenient direction. The cable is indicated by the numeral 39. This arrangement of blocks and tackle afi'ords a simple and efiicient means for raising the carrier-raising frame.

. i thep b e 01; $14911 The main supporting frame is so arranged that the beam 6 is a little to the rear of the vertical line extending through the pivot rod 9, and acts as a stop to limit the rearward movement of the carrier and its raising frame. It permits the carrier to overhang the bed of the wagon which is driven close to the rear end of the main frame.

17, 17 are merely cleats across the carrier platform to prevent slipping by the horses engaged in loading the carrier. The pivots 18, 18, are toward the rear of the platform, so that the front side is heavier both when loaded and when empty. As the carrierraising frame and the carrier are raised on the main pivot, the tendency of the carrier is to tilt down at its forward end, but is prevented from doing so by reason of the pull of the chains 37. And while these chains do not need to hold the platform level (in fact, they permit a slight tilt toward the frame), yet they do hold the platform sufficiently straight to prevent the load from spilling. As the carrier approaches the limit of its movement, the chains 37 engage the arms 8, so that the continued movement of the raising-frame tilts the rear end of the carrier downward until the final posi tion is reached as shown by the dotted out lines in Fig. 1, with the carrier at suflicient tilt to permit the load to slide off of it into the wagon bed. Also the final movement brings the handles of the lever latches 29 against the fingers 7. 7, thereby releasing the door which then falls down in line with the platform. This door prevents the load from spilling until the last moment when the carrier is in proper position to discharge its load. I also provide two rather strong coil extension springs 44 secured at one end to the cross-beam 2 at the forward end of the main supporting frame, and at the other to the diagonal braces 11 of the carrier-raising frame; though in fact part of the length of each connection may be a chain 45. These connections are of such length that they are loose or slack when the carrier is down, are taut when the raising frame is in about the position indicated by the dotted outline 46, just before the frame has come to vertical position, and are under tension during the further rearward travel of the carrier-raising frame. Their purpose is to pull back the carrier-raising frame immediately upon. the discharge of the load from the carrier, at least to a point in front of the dead center, after which the weight of the .carrier and raising frame will bring the parts back to proper position with the carrier. down and ready to receive another load. Of course, the springs should be strong enough to overcome both the weight of theframe Thecarrier andcarrier and the friction.

may be let down easily by simply paying return, the door is automatically closed by striking against the guides 33, 33.

It will now be understood that the opera tion of the several parts is entirely automatic, the only action on the part of the operator being to pull the cable to lift the carrier, and the paying out of the cable to efi'ect an easy return.
